SATELLITE ANALYSIS AND TRENDS...WATER VAPOR IMAGERY AND RAP ANALYSIS
INDICATE AN APPROACHING WEAK SHORTWAVE TO THE NORTHWEST AS WEAK DIFFLUENCE
IS SEEN IN THE MID LEVELS. VISIBLE IMAGERY INDICATES THE FORMATION OF
THE TYPICAL LAND/SEA BREEZE BOUNDARY HAVING ALREADY FORMED ALONG THE
NORTHERN PART OF THE ISLAND. SAN JUAN`S 12Z SOUNDING INDICATED AMPLE
MOISTURE (PWATS ALMOST 2 INCHES) AND A MODERATELY UNSTABLE ATMOSPHERE
(CAPE JUST OVER 1400 J/KG)  IN PLACE OVER THE REGION. THE BLENDED TPW
PRODUCT CONFIRMS THE REGIONS ABOVE AVERAGE PWATS AROUND 2 INCHES.
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10-15 MINUTES.
.
SHORT TERM OUTLOOK VALID 1505-2000Z...MEDIUM CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...GIVEN THE MOIST AND UNSTABLE ATMOSPHERE OVER
THE ISLAND AS THE SHORTWAVE APPROACHES, CONVECTION COULD POSSIBLY BE
MORE ORGANIZED THAN THE TYPICAL DIURNAL CONVECTION FOR NORTHWEST/WESTERN
PUERTO RICO DURING THE OUTLOOK PERIOD. MODERATE TO LOCALLY HEAVY RAIN IS
POSSIBLE, ESPECIALLY ALONG ANY BOUNDARIES (LAND/SEA OR POSSIBLE OUTFLOW)
THAT MAY BE PRESENT.
